Call Transaction method in BDC.

Hello all,

Call transaction TCODE using BDCDATA mode u2018Nu2019 update u2018Su2019 messages in BDCMSGCOLL.

The above statement doing two things: It calls TCODE and process database.

Here my question is, the above statement sets the SY-SUBRC value after calling the TCODE or after calling TCODE and process database.

Thanks .......

Zak.
