Hi Sashi
Do You maintain the inventory of Your Tools By Quantity wise or value wise Or Both ?
In your scenario You can apply the RTP special stock Type scenario
You maintain the Tools as RTP stock , Upload the Inventory by Initial stock (561/M ).
when ever You issue the tools to Vendor do an 502/M through MB1C tcode. When Job is over you can collect Your tools By 501/ M . RTP stock can be viewed by Stock overview Plant stock availability
