Let's get Started. Head to the user access module and open the setback Date entry modification locking schedule. The window displays a list of documents against which you can set a log date to restrict backdated entries and modifications. Let's define the log setting for the sale document. Select the sale document from the list. Right click on the selected document to open the options menu and select settings. Alternatively, you can open the settings directly by pressing the F three key. This will open the lock for back date entry window where multiple options are available to define the lock criteria. Now, let's implement the fixed days lock and observe its impact. Select the number of days you wish to restrict. This setting ensures that you will not be able to edit any bills or create backdated bills for days one, two, and three of every month. After defining the settings, click safe to apply the changes. Now let's navigate to the sale bill window and attempt to modify a bill that falls within the locked period. Let's try to modify this bill. Upon saving the changes, the software automatically restricts the action and displays an error message indicating that entry modification is locked for this period. Now let's also initiate a new transaction with a back date falling within the locked period. As observed, the software also restricts the saving of any new transaction with a back date that falls within the locked period. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/user-access.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
