Hello
The system behavior is explained on the following note:
| 303441 | MD04: No automatic refresh when changing material |
The note provides the following explanation:
Within the requirements/stock list (Transaction MD04), you change to a material which you have already displayed. The data is not imported automatically again. The system displays the data from the first call of this material.
In the status bar, the system displays message MD451 ('The list was created at XX:XX hours') and in the title, it displays the time of the last import of the material.
It also suggests the modification below, that can be implemented to prevent this system behavior:
This note contains a modification with which you can change the system behavior described above.
The size of the list (that is, the number of the lines) is used as indicator for the decision whether the requirements/stock list is read from the buffer or set up again.
Using the modification you can set up to which number of lines data should be imported again.
For this, a constant 'GC_MAXLINES' exists in program 'MM61RTOP'. This is delivered with value '0' in the R/3 Support Package. With this value the system behaves as described above.
If you, for example, enter value '200' here, then up to a number of 200 lines, the data is read from the database again. From a number of 201 lines the data is read from the internal buffer, if available.
