Idoc WBBDLD date different

Hi

While generating Idoc WBBDLD via WDBU_HPR getting different date in test system.

I am sending Idoc WBBDLD through WDBU_HPR in live system it is picking tomorrow's date but in testing system date is today's date for Field GLTAB in segment E1WBB01 of Idoc WBBDLD

I need system to pick tomorrow's date may I know where this configuration settings exist.

Regards
