Is it possible to rename a custom z-field in a SAP standard table with out loosing the data in that column? We have millions of records in that Standard table.

Yes, that should be OK! Especially if you are not changing its type.

Don't forget to re-generate the table maintenance function group/module, if any.

If you have to change type, you can adapt data with the SE14 transaction.

Best regards,

If you rename a column in your db, it is like deleting the field and adding a new one. You will loose data. Best way to do this is to add the new field, transport to production. Write a program to copy the value from the old field to the new field, then delete the old field.

Hi Sanjay

I also suggest the way to write a program to shift all data of field to be deleted to new field. You can write a simple code.

Select source field value into variable.

Target field value = variable.

Update table set target field.

Commit work.

OR you can write a BDC program if you can have the target field as any screen field.

Should be a simple program.

report zrich_0001.

data: iztab type table of ztab with header line.

select * into iztab from ztab.
loop at iztab.
iztab-newf = iztab-oldf.
modify ztab from iztab.
