FIFO layers detail requirement

Question

Hi Team,
I am facing problem for the development of costing of the fininshed
goods whihc we are manfucturing in warehouse through production module .
For my result purpose i need to know the detail of raw material whihc
actually consumed and from whihc layers based on the FIFO concept.
i am reffering to oinm table (warehouse journal) in whihc all the
detial of the material flow is present but information related to
layers from whihc the items are consumed actually ,
this information is missing in oinm due to whihc my link
development is not proper and i am
facing problem to track the actual consumption FIFO wise.
so kindly provide me the infromation how to get the data of layers 
for eg. the layer information should be like
GRPO 20(doc No OF GRPO) and 3(line no of GRPO 20)
so that technical developer can easily identify the layer of the rawmaterial from oinm table for the consumed item.
i am at live stage and customer requiremeent is
suffering very much due to this missing information in oinm system
table.

Hi Amit
The system uses a "Lot" to control the FIFO layers, although this is not physically represented by a separate table or structure. In the OINM table you will find a field called OpenQty which will indicate which FIFO layers (or costs) have not yet been consumed or sold either partially or in full. SAP Business One checks for OpenQty by date and consumes from the oldest "Lot" first. Writing a query or getting the "Lot" information could be tricky but I would suggest using the DocDate & DocTime with the OpenQty to determine what is still available and what production would consume.
