Welcome
I have a schedule of movements (Move)
I have four tables (BookIn - BookOut _ MsgIn - Msg Out)
There is a need to link the four accounts together in case there is a response to one of the existing book numbers
For example, create a text box for linking in which the desired book number, which is located in one of the four tables, is placed
Example: There is a book in the BookIn table with the number 2, which is a response to a book in MsgOut with the number 3
They must be linked together, and there is a button called the firsts. When you click on it, all the linked correspondence appears, and it may reach a large number, such as a response or an answer.
