I asked about the language indicator as for some languages the indicator is different than expected, e.g. english = EN in the screens and only E in the database,
Chinese = ZH in the screen but just 1 in the database
This meas if you entered ZH in the source then it is moved as Z to the structure and since Z is not equal to 1 you may get error messages.
Ok, if you just use English then this should not be the problem.
I asked about other fields, because the structure for the material description in BMMH5, and this has beside of MAKTX and SPRAS the fields STYPE and SPRAS_ISO
If you only maintained your material text in BMM00 but missed it in BMMH5, then SAP will complain with an error message, as BMMH5 makes the description field empty if you do not submit the description again.
So you have to decide if you use BMMH5 structure (which is a must if you want the description in multiple languages) and fill all expected fields or if you remove BMMH5 from your structure relation
