• What is the cause and solution for SAP error message MDG_BS_MAT_API021 - Price control indicator and price cannot be changed simultaneously ?

  The SAP error message MDG_BS_MAT_API021 indicates that there is an issue with changing both the price control indicator and the price of a material simultaneously in the Master Data Governance (MDG) system. This error typically arises when there are conflicting changes being made to the material master data.
  
  Cause:
  The error occurs because the price control indicator (which determines how the material's price is managed) and the price itself are interdependent fields. In SAP, the price control indicator can be set to different values (like Standard Price or Moving Average Price), and changing the price control indicator while also trying to change the price can lead to inconsistencies in how the material's valuation is handled.
  
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Separate Changes: Make changes to either the price control indicator or the price, but not both at the same time. 
  
  First, change the price control indicator and save the changes.
