The SAP error message SLS036 ("Test structure can only deviate by items") typically occurs in the context of SAP's Sales and Distribution (SD) module, particularly when dealing with sales documents, pricing, or conditions. This error indicates that there is an issue with the structure of the test data or the way the items are being processed in a sales document.
Cause:
The error usually arises due to one of the following reasons:
Inconsistent Item Structure: The test structure of the sales document does not match the expected structure defined in the system. This can happen if there are discrepancies in the item categories or if the items are not properly aligned with the pricing or condition records.
Deviation in Item Data: The system expects that deviations in the test structure should only occur at the item level. If there are deviations at a higher level (like header level), the system will throw this error.
