Amalendu,
Please elaborate your question. A shipping point can affect the timing of the goods issue, which indirectly affects stock.
In general, a shipping point is typically determined in the sales documents at some point during the life of the sales order. If a shipping point is determined, it can be used to affect the scheduling (timing) of certain stock-relevant events in the life of the sales document.
However, when it becomes time to actually perform a Goods Issue (stock transaction) against the sales document, the shipping point is generally irrelevant. Goods issues are done against MM objects, such a Plants or storage locations. Stock is in general not held in a Shipping Point. The resultant material documents that are generated will generally not contain anything about the shipping point in standard SAP,
