BAPI_PO_CREATE1 error message

Hi;

When executing the BAPI_PO_CREATE i'm getting this error message.

TYPE ID NUMBER MESSAGE

E TD 600 Text * ID * language * not found.

The error is in POHEADER structure

i'm passing values to table POTEXTHEADER too

PO_ITEM TEXT_ID TEXT_FORM TEXT_LINE

00010 F01 my text

I'm not sure what could be the problem, because it happens from time to time, not always.

Thanks on advance,
