PO text(Header and Item) OMQ6 and CG3Y

Hi All

We are running Tcode OMQ6 and Then CG3Y to get the text present in header and item level for set of POs. now i have done this for almost 1000 POs out of which for 20-30 POs syetem is not giving correct result.

actually for these POs text is present at item level but OMQ6 is not transferring this to loacl file or we can say it is not considering these PO.

I am wondering what can be the possible reason for this, if anybody have worked on this and got similar issue the appreciate your fast reponse.

Regards

Yogesh
