How To Fix TB527 - Only right-generic key patterns possible

SAP Error Message - Details

• Message type: E = Error

• Message class: TB - SM31 table maintenance messages

• Message number: 527

• Message text: Only right-generic key patterns possible

What causes this issue?

In order to restrict the comparison to a manageable number of view
entries you can specify a right-generic key pattern. This means that
you may only use the generic character '*' as the last character of the
whole key pattern. The whole key pattern emerges when you write the
contents of the individual key fields behind each other.
Note that an empty field of the whole key pattern before the generic
character is interpreted as a sequence of blank characters and not as a
place holder for arbitrary characters. In order to select all view
entries enter the generic character '*' in the first (non-numeric)
field. No generic entry is possible in numeric fields and date fields.

• What is the cause and solution for SAP error message TB527 - Only right-generic key patterns possible ?

  The SAP error message TB527 "Only right-generic key patterns possible" typically occurs in the context of defining key patterns for certain database operations, particularly when working with table fields or indexes in the SAP system. This error indicates that the key pattern you are trying to define is not valid because it does not conform to the expected format.
  Cause:
  The error is usually caused by one of the following issues:
  
  Incorrect Key Pattern Definition: The key pattern you are trying to use is not a right-generic pattern. In SAP, a right-generic key pattern means that the key can end with a wildcard (e.g., *), but cannot start with one.
  Misconfiguration in Table or Index: If you are trying to create or modify a table or index and the key pattern does not follow the required conventions, this error will be triggered.
  Data Dictionary Issues: Sometimes, the error can arise from inconsistencies or misconfigurations in the data dictionary.
  
  Solution:
  To resolve the TB527 error, you can take the following steps:
  
  
  Check Key Pattern: Review the key pattern you are trying to define. Ensure that it is a right-generic pattern. For example, valid patterns include ABC* or XYZ*, but not *ABC or *XYZ.
  
  
  Modify Key Definition: If you are defining a key in a table or index, modify the key definition to conform to the right-generic pattern rules.
  
  
  Review Data Dictionary: If you are working with a custom table or index, check the data dictionary entries for any inconsistencies. You can use transaction codes like SE11 (Data Dictionary) to review and modify the definitions.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on defining key patterns correctly.
  
  
  Testing: After making the necessary changes, test the operation again to ensure that the error has been resolved.
