How To Fix CM_REPORT_TEMPLATE180 - Symbol &1 of instance control occurs more than once in output block

SAP Error Message - Details

• Message type: E = Error

• Message class: CM_REPORT_TEMPLATE - Report Templates

• Message number: 180

• Message text: Symbol &1 of instance control occurs more than once in output block

What causes this issue?

An error message is output when a new report body is created with the
selected report template.
An output block in which the &V1& symbol for instance control occurs
more than once was defined for an MIC repeating group (master group with
instance control) or an MIC:POS repeating group (master group -
positions of instance control). However, this symbol may occur only once
within the MIC repeating group or the MIC:POS repeating group.
The report template therefore cannot be used for report generation.

System Response

How to fix this error?

Remove the redundant &V1& symbols from the MIC repeating group or the
MIC:POS repeating group so that an output block is denoted by one
EHS_ICBCB start symbol and one EHS_ICBCE end symbol.
Example:
<NP><(><<)>11BRG015(MIC,SAP_EHS_1027_001;*)><(><<)>01EHS_ICBCB></>
[Data for the output block]
<NP><(><<)>01EHS_ICBCE><(><<)>11ERG015></>

• What is the cause and solution for SAP error message CM_REPORT_TEMPLATE180 - Symbol &1 of instance control occurs more than once in output block ?

  The SAP error message CM_REPORT_TEMPLATE180 indicates that there is a problem with the output block of a report template, specifically that a symbol (in this case, &1) of an instance control is being referenced more than once. This typically occurs in the context of SAP's reporting tools, such as SAP Crystal Reports or SAP Smart Forms, where the output format is defined using templates.
  Cause:
  
  Duplicate Symbols: The error is primarily caused by having the same symbol (e.g., &1) defined multiple times within the same output block. This can happen if the report template is incorrectly configured or if there are multiple references to the same data field without proper differentiation.
  Incorrect Instance Control: The instance control may be set up in a way that it tries to display the same data element multiple times in a single output block, which is not allowed.
  
  Solution:
  
  Check the Report Template: Open the report template in the design tool (e.g., SAP Crystal Reports or Smart Forms) and look for the output block where the error is occurring. Identify the symbol &1 and check if it is being used more than once.
  Remove Duplicates: If you find that the symbol is duplicated, remove the extra instances or modify the design to ensure that each symbol is unique within the output block.
  Modify Instance Control: If the instance control is incorrectly set up, adjust it to ensure that it only references the symbol once within the output block.
  Test the Report: After making the necessary changes, save the report template and run the report again to see if the error persists.
