• What is the cause and solution for SAP error message CY050 - You cannot use the operator BT ?

  The SAP error message CY050, which states "You cannot use the operator BT," typically occurs in the context of SAP's configuration for controlling or production planning, particularly when dealing with certain types of data selection or filtering.
  Cause:
  The error message CY050 is triggered when the system encounters an invalid use of the "Between" (BT) operator in a selection criterion. This can happen in various scenarios, such as:
  
  Invalid Data Type: The operator BT is used with a data type that does not support range selection. For example, using it with a character field or a field that does not have a defined range.
  Incorrect Field Context: The field you are trying to apply the BT operator to may not be appropriate for that context, such as in a report or selection screen where the field is not designed to handle range queries.
  Missing Values: If the values you are trying to use with the BT operator are not properly defined or are missing, the system will not be able to process the request.
  
  Solution:
  To resolve the CY050 error, you can take the following steps:
  
  
  Check Data Types: Ensure that the field you are applying the BT operator to is of a data type that supports range selection. For example, numeric or date fields typically support this operator.
  
  
  Review Selection Criteria: Go through the selection criteria in your report or transaction and verify that the fields are correctly defined. Make sure that you are not trying to use the BT operator on fields that do not support it.
  
  
  Provide Valid Values: Ensure that you are providing valid and complete values for the range you are trying to define. Both lower and upper limits should be specified.
  
  
  Consult Documentation: If you are unsure about the fields and their capabilities, refer to the SAP documentation or help resources related to the specific module you are working with.
  
  
  Test with Different Operators: If the BT operator is not necessary for your use case, consider using other operators like EQ (Equal) or NE (Not Equal) to see if that resolves the issue.
