• What is the cause and solution for SAP error message MDMXFW026 - Selection operator SIGN must be the same for all entries ?

  The SAP error message MDMXFW026 indicates that there is an inconsistency in the selection criteria used in a query or report, specifically regarding the use of the SIGN operator. This error typically arises when you are trying to filter data using multiple selection criteria, and the SIGN (which indicates whether the selection is to include or exclude records) is not consistent across all entries.
  
  Cause:
  The error occurs when:
  
  You have multiple selection criteria (for example, in a selection screen or a report) where the SIGN operator (e.g., I for include, E for exclude) is not the same for all entries.
  For instance, if you have one selection criterion set to include records (I) and another set to exclude records (E), SAP cannot process this request because it leads to ambiguity in the selection logic.
  
  
  Solution:
  To resolve this error, you should ensure that all selection criteria have the same SIGN operator. Here are the steps
