How To Fix COM_PME_PARSER025 - Syntax error in constraint

SAP Error Message - Details

• Message type: E = Error

• Message class: COM_PME_PARSER - Configuration

• Message number: 025

• Message text: Syntax error in constraint

What causes this issue?

During the syntax check the system found errors in the constraint. This
could have the following causes:
Consider that, in general, you can only use keys (characteristic,
class, table and function names) that contain hyphens with the addition
SKEY. The key name appears in quote marks.
SKEY 'EXT-COLOR'
The system also does not always recognize changes to master data that
are made parallel to dependency maintenance. This is due to data
puffering.
Consider that character strings (for example, characteristic values of
characteristics with the format CHAR) appear in quote marks: COLOR =
'RED'. The values of numeric characteristics do not appear in quote
marks.
The individual sections of a constraint are introduced using the
relevant key word and a colon, for example, OBJECTS:
If you define variables for several characteristics, the
characteristics are separated from each other using a semicolon. The
individual objects are separated by a comma.
An example for a constraint is included below.

System Response

The cursor marks the error. If necessary, several detailed causes of
error will be listed for selection.

How to fix this error?

Check your entry and correct the error. You have the following options
for analysing and solving errors:
If you cannot immediately recognize the cause of the error, choose a
detailed message that seems suitable using the <ZH>Details</>
pushbutton. The cursor is positioned accordingly in your source code
and you can, if necessary, view the long text for the detailed message
for further information. If the detailed message selected is not
suitable, you can repeat the checking procedure and choose a different
detailed message. You can find an example of a constraint below.
If the system does not recognize changes to master data that were made
parallel to maintenance of object-dependencies, restart maintenance.
You can also save the source text for the dependency if the syntax
remains incorrect. The system then sets the status of the dependency to
<ZH>Locked</> and the dependency is not available for configuration.

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

Constraint example:
OBJECTS:
?S IS_A (300)STAIRCASE
WHERE ?A = ANGLE; ?HB = HEIGHT_BANNISTER,
?P IS_A (200)POST
where ?HP = HEIGHT; ?PTS = POSITION_ON_STEP.
CONDITION:
PART_OF(?P, ?S).
RESTRICTION:
?HP = ?HB+?PTS*TAN(2*3.14/360 * ?A).
INFERENCES:
?HP, ?HB, ?PTS
Example of how an object is declared in a constraint:
OBJECTS:
?O IS_OBJECT
(DOCUMENT)(017)(TYPE=DRW, VERSION=00, PART=000, NR='ST-12345'),

• What is the cause and solution for SAP error message COM_PME_PARSER025 - Syntax error in constraint ?

  The SAP error message COM_PME_PARSER025 indicates a syntax error in a constraint definition, typically within the context of the SAP Product Master or similar applications where constraints are defined for product characteristics or configurations.
  Cause:
  
  Incorrect Syntax: The most common cause is that the syntax used in the constraint definition is incorrect. This could be due to missing operators, incorrect use of parentheses, or invalid expressions.
  Invalid Characters: The presence of invalid characters or symbols that are not recognized by the parser can lead to this error.
  Logical Errors: Sometimes, the logical structure of the constraint may be flawed, such as referencing non-existent characteristics or using incompatible data types.
  Version Issues: If the system has been recently upgraded or patched, there may be changes in how constraints are processed, leading to previously valid constraints becoming invalid.
  
  Solution:
  
  Review the Constraint Definition: Go through the constraint definition carefully to check for any syntax errors. Ensure that all operators and expressions are correctly formatted.
  Check for Invalid Characters: Make sure that there are no invalid characters or symbols in the constraint.
  Validate Logic: Ensure that the logic of the constraint is sound. Check that all referenced characteristics exist and are compatible.
  Use the Syntax Checker: If available, use any built-in syntax checking tools in SAP to validate the constraint before saving it.
  Consult Documentation: Refer to SAP documentation or help resources for the correct syntax and examples of valid constraints.
  Test in a Development Environment: If possible, test the changes in a development or sandbox environment before applying them to production.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions to common problems.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed.
  Transaction Codes: Familiarize yourself with relevant transaction codes (like CT04 for characteristics, CU01 for configuration profiles) that may help in managing constraints and characteristics.
  Training and Documentation: Consider additional training or reviewing documentation on SAP Product Configuration and constraint management to better understand how to define and troubleshoot constraints.
  
  If the issue persists after following these steps, it may be beneficial to reach out to SAP support for further assistance.
