How To Fix D9436 - ALE pointer for table &1 with RECN_LOC/ACTN_LOC &2 exists already

SAP Error Message - Details

• Message type: E = Error

• Message class: D9 - Environment Management System

• Message number: 436

• Message text: ALE pointer for table &1 with RECN_LOC/ACTN_LOC &2 exists already

What causes this issue?

An ALE pointer could not be inserted into table ESTALE, because a line
exists already with the same primary key or with a unique secondary
index in the database table. The unique key of the table ESTALE is made
up of the fields MANDT, RECN_LOC, ACTN_LOC, and ALE_OBJECT. However, the
ALE pointer that was not inserted contains the following values:
,,MANDT,,,,,,= Client Number
,,RECN/ACTN,,,,= &V3&
,,LOGSYS,,,,= logical system name of the ALE source system
,,ALE_OBJECT,,,,= <LB>S</> for specifications or <LB>P</> for phrases
,,OBJECTID,,,,= &V4&
,,RECN_LOC/ACTN_LOC,,= &V2&
,,TABLENAME,,,,= &V1&

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

The error can occur because of varying reasons, for example,
The primary key (RECN field) of a data record is determined using the
number range ESN_RECN. A number range that was set up incorrectly can
cause a number to be determined that is already used in the respective
table as the primary key. The system fails to create a data record. To
check the number range, perform the following:
Determine the current number of the number range ESN_RECN, Interval
<LB>01</>. To do so , start transaction SNRO, specify the object name
ESN_RECN, and choose <LS>Display</>. Then, choose the menu option
<LS>Goto</> -> <LS>Number Ranges</> and click <LS>Display Intervals</>.
Make a note of the number in the <LS>Current Number</> field for
interval <LB>01</>. This number contains the primary key that was last
assigned for a data record.
Next, check whether database table ESTALE contains primary keys
(RECN_LOC field) that have a value greater than or equal to the number
you noted from number range ESN_RECN. To do so, start transaction SE16N,
enter the relevant table, and define the selection criterion RECN_LOC >=
current number of number range ESN_RECN. Then, start the search.
If you find values, you must adjust the number range in such a way that
the current number of the number range ESN_RECN (interval 01) is greater
than the highest number in the RECN_LOC field in table ESTALE. To adjust
the number range, you can use the transaction SNRO again. If no values
were found, the ALE pointer cannot be created again because of another
problem.
This error can occur when certain data records were deleted logically
(delete indicator is set), but not physically. For this reason, you must
run the reports <LS>Set Missing Deletion Indicator and Physically Delete
Data</> (RC1PHDEL) on the ALE target system and select the <LS>Set
Deletion Ind.</> and <LS>Physically Delete</> parameters. Also refer to
the Customizing activity
<DS:SIMG.EHS_MD_110_05_7>Set Up Job for Deleting Data</> and the
information about running report RC1PHDEL in the Customizing activities
<DS>
<DS:SIMG.EHS_MD_120_40_02>Set Up Distribution of Specification Data</>
</>,
<DS:SIMG.EHS_MD_140_40_04>Set Up Distribution of Phrase Data Between
Systems</>, and
<DS:SIMG.EHS_MD_150_40_01>Set Up Distribution of Reports</>. After you
have executed the report, you can post the incorrect IDoc with
transaction BD87 again.

• What is the cause and solution for SAP error message D9436 - ALE pointer for table &1 with RECN_LOC/ACTN_LOC &2 exists already ?

  The SAP error message D9436 indicates that there is a conflict with the ALE (Application Link Enabling) pointer for a specific table. This error typically arises when there is an attempt to create or modify an ALE pointer for a table that already has an existing pointer with the same location and action.
  Cause:
  The error occurs due to the following reasons:
  
  Duplicate Pointer: An ALE pointer for the specified table (&1) with the given location (RECN_LOC) and action (ACTN_LOC) already exists in the system.
  Configuration Issues: There may be misconfigurations in the ALE settings or the distribution model that lead to attempts to create duplicate pointers.
  Data Consistency Issues: There might be inconsistencies in the data or configuration that cause the system to believe that a pointer needs to be created when it already exists.
  
  Solution:
  To resolve the D9436 error, you can follow these steps:
  
  
  Check Existing Pointers:
  
  Use transaction code WE20 (Partner Profiles) or WE21 (Port Definition) to check the existing ALE pointers for the specified table.
  Look for the pointer with the same RECN_LOC and ACTN_LOC values.
  
  
  
  Delete or Modify Duplicate Pointer:
  
  If you find a duplicate pointer that is not needed, you can delete it.
  If the pointer is required, ensure that the configuration is correct and that you are not trying to create a new pointer unnecessarily.
  
  
  
  Review Distribution Model:
  
  Check the distribution model using transaction BD64 to ensure that the settings are correct and that there are no conflicting entries.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to ALE configuration to ensure that you are following the correct procedures.
  
  
  
  System Logs:
  
  Check system logs for any additional error messages or warnings that might provide more context about the issue.
  
  
  
  Contact SAP Support:
  
  If the issue persists and you cannot identify the cause, consider reaching out to SAP support for further assistance.
