Query regarding VL06G

Dear Gurus,

Before 3 yrs there are some inv. generated without doing PGI in delivery.

out of some reflecting VL06G while entering batch, some are not reflecting in report. Is there any reson. PGI is pending for all.

Ex. delivery 1 , 2 , 3 with respective batch x , y , z

Delivery saved but pgi is pending.

Now through VL06G delivery 1 & 2 is coming for batch X and Y

But for delivery 3 and batch Z vl06g is not getting output.

For batch Z I cal also check the stock in mmbe under Schd. For delivery.

Please advise for same.

Thanks & Regards

Rajan
