• What is the cause and solution for SAP error message REP_EAPS_MSG128 - Only simple items are allowed for this type of line ?

  The SAP error message REP_EAPS_MSG128 ("Only simple items are allowed for this type of line") typically occurs in the context of creating or processing documents in SAP, such as purchase orders, sales orders, or other transactional documents. This error indicates that the system expects only simple items (i.e., items that do not have any sub-items or complex structures) for a specific line type, but the input provided does not meet this requirement.
  Cause:
  
  Line Type Mismatch: The line type you are trying to use may not support complex items. For example, if you are trying to add a service item or a configurable item where only standard material items are allowed.
  Item Category Configuration: The item category configuration in the material master or document type may restrict the use of complex items.
  Document Type Restrictions: Certain document types may only allow simple items due to business rules or system configurations.
  
  Solution:
  
  Check Item Type: Ensure that the item you are trying to add is a simple item. If you are trying to add a service or a configurable item, consider changing it to a standard material item if applicable.
  Review Document Type and Item Category: Verify the document type and item category settings in your SAP configuration. Ensure that they are set up to allow the types of items you are trying to use.
  Consult with Configuration Team: If you are unsure about the settings, consult with your SAP configuration team or a functional consultant to review the item category settings and document type configurations.
  Use Correct Item Category: If you need to use a complex item, ensure that you are using the correct item category that supports such items.
  Test with Different Items: Try creating the document with different items to isolate the issue and confirm that the error is related to the specific item type.
