+"""
+This patch is written to fix Stock Ledger Entries and GL Entries 
+against Delivery Notes and Sales Invoice where Target Warehouse has been set wrongly
+due to User Permissions on Warehouse.
+
+This cannot be run automatically because we can't take a call that 
+Target Warehouse has been set purposefully or by mistake. 
+Thats why we left it to the users to take the call, and manually run the patch.
+
+This patch has 2 main functions, `check()` and `repost()`. 
+- Run `check` function, to list out all the Sales Orders, Delivery Notes 
+	and Sales Invoice with Target Warehouse.
+- Run `repost` function to remove the Target Warehouse value and repost SLE and GLE again.
+
+To execute this patch run following commands from frappe-bench directory:
+```
+	bench --site [your-site-name] execute erpnext.patches.v6_12.repost_entries_with_target_warehouse.check
+	bench --site [your-site-name] backup
+	bench --site [your-site-name] execute erpnext.patches.v6_12.repost_entries_with_target_warehouse.repost
+```
+
+Exception Handling:
+While reposting, if you get any exception, it will printed on screen. 
+Mostly it can be due to negative stock issue. If that is the case, follow these steps
+	- Ensure that stock is available for those items in the mentioned warehouse on the date mentioned in the error
+	- Execute `repost` funciton again
