The SAP error message FINCS_MD_FSITEM102 indicates that there is an issue with processing multiple financial statement item assignment operations within a single changeset. This typically occurs in the context of financial statement item management in SAP, particularly when using the Financial Statement Item (FS Item) assignment functionality.
Cause: The error arises when you attempt to perform multiple operations (like create, update, or delete) on financial statement items in a single transaction or changeset. SAP restricts this to ensure data integrity and consistency, as processing multiple operations simultaneously can lead to conflicts or unexpected results.
Solution: To resolve this error, you can take the following steps: Separate Changesets: Instead of trying to process multiple FS item assignment operations in one changeset, break them down into individual changesets. Each operation should be executed in its own transaction. Batch Processing: If you are using batch processing, ensure that each batch only contains one type of FS item assignment operation.
