Field not getting save from table to transparent table in SAP

When working with SAP tables and transparent tables, you may encounter issues where fields are not getting saved properly. What can be understood from this problem is not a type mismatch but rather a mismatch in field size, as defaults are different for each table type.

Understanding the Size Mismatch Issue

In SAP, when you create fields in different table types, the system assigns default sizes that may not always match. This discrepancy can prevent data from being saved correctly when transferring information between a regular table and a transparent table.

Solution

To resolve this issue, you need to adjust the field sizes to match your requirements. Here are the steps to follow ?

Steps to Fix Field Size Mismatch

Follow these steps in the SAP Data Dictionary (SE11) ?

1. Go to SE11 (ABAP Dictionary)
2. Open your transparent table
3. Check the field lengths in both tables
4. Modify the field size to match the source table
5. Activate the changes
6. Test the data transfer again

Example Field Configuration

Ensure that corresponding fields have matching specifications ?

Source Table Field: MATNR CHAR(18)
Target Transparent Table Field: MATNR CHAR(18)

// Instead of mismatched sizes like:
Source: MATNR CHAR(18)
Target: MATNR CHAR(10)  // This will cause save issues

Conclusion

By ensuring that field sizes match between your source table and transparent table, you can resolve the save issues and ensure proper data transfer in SAP systems.
