• What is the cause and solution for SAP error message M3528 - Value will be reset (in-house prod. time dep. on lot size exists already) ?

  The SAP error message M3528, which states "Value will be reset (in-house prod. time dep. on lot size exists already)," typically occurs in the context of production planning and control within the SAP system. This error is related to the configuration of in-house production times that are dependent on lot sizes.
  Cause:
  The error arises when there is an attempt to change or set a value for in-house production time in a material master record or a routing, but the system detects that there is already a dependency on lot size defined for that material. In other words, if there are existing settings that specify different production times based on different lot sizes, the system will not allow you to set a fixed value for in-house production time, as it would conflict with the existing lot size-dependent settings.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Settings: 
  
  Go to the material master (transaction code MM03) and check the production data for the material in question. Look for any existing lot size-dependent production times.
  Review the routing (transaction code CA03) to see if there are any operations with lot size-dependent times.
  
  
  
  Adjust Lot Size Dependencies:
  
  If you need to set a fixed in-house production time, you may need to remove or adjust the existing lot size-dependent settings. This can be done in the material master or routing, depending on where the dependency is defined.
  If you want to keep the lot size-dependent settings, you should enter the production times according to the defined lot sizes.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help files related to production planning and material master data to understand how in-house production times and lot sizes interact.
  
  
  
  Consult with a SAP Consultant: 
  
  If you are unsure about making changes or if the issue persists, it may be beneficial to consult with a SAP functional consultant who specializes in production planning.
