Since the source data is in SAP and you want to fetch this data into delivery screen which is also in SAP, through IDOC, this can be achieved.
Sir-Among SAP applications also we can use IDOCs-Very interesting 
Please let us know on what kind of business scenarios-we will use the above process--Your expertize will help us a lot here sir.
On seeking additional Info--I asked this to my abaper & he replied in SAP-among Sales Order & Delivery applications also we can use interfaces like IDOCs & RFCs..normally these are used between Non-SAP application to SAP applications.But always functional guys need to achieve this with Standard methods.
we are also having the same Barcode implementations in our client.Once any sales order created there will be a CSV file from SAP to Barcode central path via PI-Then from Central to respective plant/Godown's Barcode gun-Once scanning done with Barcode gun by godown Labour--He will save in the gun itself-then via Central path & PI-there will be calling for VL01n Tcode in SAP by one communication user(where User name or password doesn't exists for this communication user)--Then the batches scanned will be kept in SAP Batch split tab by using one BDC followed by save.
Once after saved- the delivery user will check in VL02n with some mandatory texts followed by PGI.
Here also we are following Auto Invoice functionality along with PGI.
But here our member is creating a custom table update with packing slip details from Barcode-then delivery creations with these details--may be he can follow the above procedure of us.
Dear pramod-May i know why are you updating custom table for Packing slips??
