-In a warehouse environment, stock may be received in 'bulk' (large pack sizes), then physically broken down in to smaller, 'issue size' packs, **//without telling mSupply//** through a "Repack" or "Split".  The stock may then be issued without paying attention to the pack sizes.
+===== Introduction =====
+In a warehouse or dispensary, stock may be received in 'bulk' (larger pack sizes) which then need to be physically and logically broken down in to smaller, 'issue size', packs before the stock is issued.  It often makes sense to keep last-expiring stock in bulk quantities until closer to the time it will be issued:
+  * It makes for easier stock-taking; just counting the number of cartons, rather than working out how many inner packs are in the cartons, and then multiplying that by the number of cartons.
+  * If you will be [[items:splitting_a_stock_line|splitting a stock line]] to move a carton(s) to a more accessible location for issue, then keeping the 'carton' pack size makes it easier to identify how much stock needs to be to split off.
+In any case, whenever it is done, you will need to change the pack size of your stock.
+<WRAP center round important 60%>
+It is important that changing pack size does **NOT** change the total amount of stock that you have.  mSupply is carefully designed to ensure this.
+However, if you have accidentally told mSupply that you have issued more stock than you actually have, then mSupply does allow for these to be corrected through the process described in [[faq:how_to_correct_packsize#changing_pack_size_for_stock_already_issued|Changing pack size for stock already issued]], below.

+===== Changing pack size for stock on hand =====
+The pack size for Stock on hand is changed through either of two methods:
+  * [[items:repacking|Repack items]]
+  * [[items:splitting_a_stock_line|Splitting a stock line]]
+===== Changing pack size for stock already issued =====
+If your staff have forgotten to tell mSupply about the new pack size through a [[items:repacking|Repack]] or [[items:splitting_a_stock_line|Split]], then stock may be issued without noticing the large pack sizes.  This will result in mSupply being told that much more stock has been issued than actually has been.
 In an pharmacy environment, the same could also be true if the [[admin:dispensary_installation#pack_to_one|'Pack to one' preference]] has not been set.  Most users tend to rely on the stock being introduced to the system in the correct pack sizes (suitable for patient consumption) and when this is not done, the dispenser doesn't pay attention to the pack sizes and accidentally tells mSupply that they are issuing stock with large pack sizes.

 In both cases the customer or patient receives drug quantities that are generally much less than what mSupply has been told.
-It is **//much//** better to take measures to ensure that these errors do not occur frequently, but mSupply does have the facility to correct the pack size for stock that has already been issued.  This is a powerful and potentially harmful feature and so there is a special user permission to allow this.  Only high level users should have the appropriate user permissions to carry out the task below.
