LM00 --- LM04 Screen Enhancement

Question

Hi All,
I need to place a custom screen before calling the Transaction LM04 through LM00. I have configured the custom screen 1212 against the logical screen both for 0212 for 8x40 and 16X20 screen formats.
And I have placed the sub screen through the user exit in SAPLXLRF. So when I am logging to LM04 through LM00 my custom screen is getting called but once I want to move to the logical screen 0212 the system says no logical screen is found. So in turn my custom screen is getting displayed as the PBO is getting called.
Could any one please put some though on this. Though I know its difficult to visualize the problem but in brief which I need is to display the custom screen just before the main screen for LM04 and on PAI on my custom screen I want to show the main screen for LM04.
Thanks,
Somnath

Hi Shiv,
Yeps sure I would share the solution.
Actually the screen enhancement in LM is bit different as compared to that of other transactions.
Step 1 >>>>>
First we need to find the customer sub screen available where I can put our own sub screen.
For e.g. if we need to Enhance LM04 first screen, then we have modify the screen 0212. The avaibale custom sub screen would be 1212.
Step 2 >>>
In SPRO go to Logistic Execution > Mobile data Entry > Define Screen Management. Here we have to create an entry with SAPLLMOB and new variant say 1. (By default, sap will provide 0 and please don't change this entry).
Basically make sure that all the table from T3130A - T3130G are properly updated (Not required to maintain all the tables, it depends on your requirement).
Step 3 >> Its basically not to include as a step as all we know that we need to activate the enhancements in CMOD.
Stpe - 4 >> Login to LM04 you will find that the new variant 1 would be considered and all the available functionality would be kept intact with your customized sub screen. One thing make sure you have to copy the original screen 0212 as for e.g.
So enjoy with the new screen.
