  • What is the cause and solution for SAP error message 37809 - Fixed step loop not allowed next to a variable (step loop unchanged) ?
    The SAP error message 37809, "Fixed step loop not allowed next to a variable (step loop unchanged)," typically occurs in ABAP programming when there is an issue with the structure of your loop statements, particularly when using nested loops or when defining step loops in a way that is not allowed by the ABAP language rules.
    
    Cause: This error arises when you have a fixed step loop (using LOOP AT ... INTO ...) that is incorrectly placed next to a variable step loop (using LOOP AT ... without a fixed step). In ABAP, you cannot have a fixed step loop immediately followed by a variable step loop without proper separation or structure. This is because the ABAP runtime expects a specific structure for loops, and mixing these types can lead to ambiguity in how the data is processed.
    Solution: To resolve this error, you need to ensure that your loop structures are correctly defined.
