• What is the cause and solution for SAP error message WE236 - Check digit not allowed for EAN & since EAN cat. & for int. asgnmt only ?

  Certainly! Here's a detailed explanation of the SAP error message WE236:
  
  SAP Error Message: WE236
  Message Text:
  
  Check digit not allowed for EAN & since EAN category & for internal assignment only
  
  Cause
  This error occurs during the processing of IDoc segments (usually in inbound or outbound processing involving EAN/GTIN numbers) when the system detects that a check digit is included in an EAN (European Article Number) where it is not allowed.
  More specifically:
  
  The EAN number is being processed in a context where only the internal assignment of EANs without check digits is allowed.
  The system expects the EAN number without the check digit because the check digit is either calculated internally or not required for the specific EAN category.
  The EAN category involved is configured to accept only EANs without check digits for internal assignment.
  The error is triggered when the EAN number contains a check digit but the category or process expects the EAN number without it.
  
  
  Explanation
  
  EAN (European Article Number) is a barcode standard, typically 13 digits (EAN-13) or 8 digits (EAN-8).
  The last digit of an EAN is a check digit, used to verify the integrity of the number.
  In SAP, depending on the configuration and the EAN category, the system may require the EAN number without the check digit because it calculates or validates the check digit internally.
  If an EAN with a check digit is passed where only the EAN without the check digit is allowed, the system throws this error.
  
  
  Solution
  
  
  Check the EAN number format in the IDoc or master data:
  
  Ensure that the EAN number sent or maintained does not include the check digit if the EAN category requires internal assignment.
  Remove the check digit from the EAN number before sending or storing it.
  
  
  
  Review EAN category configuration:
  
  Go to transaction SPRO ? Logistics General ? Material Master ? Settings for EAN/UPC ? Define EAN Categories.
  Check the settings for the relevant EAN category.
  If the category is set for internal assignment only, then the EAN number should be without the check digit.
  If external EAN numbers with check digits are to be accepted, adjust the category settings accordingly.
  
  
  
  Adjust the process or mapping:
  
  If the EAN numbers come from an external system or IDoc, modify the interface or mapping logic to strip the check digit before passing the EAN to SAP.
  Alternatively, if the check digit is required, change the EAN category to allow external EANs with check digits.
  
  
  
  Check for user exits or BADIs:
  
  Sometimes, custom code may be involved in processing EANs.
  Verify if any user exits or BADIs are manipulating EAN numbers incorrectly.

  Additional Tips:
  
  Understand the business process: whether EANs are assigned internally by SAP or externally by vendors.
  Ensure consistency in EAN number formats across systems.
