Blue Harbors – Customizing SAP RF Mobile Screens

4/15/2014Blue Harbors – Customizing SAP RF Mobile Screens BLOG B H CA RE E RS S UB M I T RFP Home Services Industries Company Connect Customizing SAP RF Mobile Screens ITSmobile is SAP’s current technology base for connecting mobile devices to SAP systems. It’s based on SAP Internet Transaction Server (ITS) and has been shipped as part of the Netweaver platform since Netweaver 2004. ITSmobile provides a framework for generating HTML browser based screens for any SAP transaction. For the purpose of this blog, we will focus the RF mobile (LMxx) transactions, which are designed to support various warehouse processes. The RF mobile transactions typically don’t fit nicely on mobile devices, and are often missing data fields and functionality needed to support the business process. For this reason, customization is nearly always needed to meet the business needs, and to optimize the screens for the mobile devices selected. From the IMG, Logistics Execution->Mobile Data Entry is the entry point for RF mobile customization. From there we select Define Screen Management to retrieve the logical and original screen numbers of the screen we wish to customize. The RF mobile screens are typically implemented in the SAPLLMOB module pool (function group LMOB). In this example we will customize the LM00 logon screen, which is logical screen 889, original screen 0889 for the narrow format. Copy the original screen from function module LMOB screen 0889 to “exit” function module XLRF, screen 9889 (standard practice is to substitute the first digit of the original screen number with a 9). Change the new screen to a subscreen and remove the ok code. http://blueharbors.com/customizing-sap-rf-mobile-screens/ 1/6 4/15/2014 Blue Harbors – Customizing SAP RF Mobile Screens Then reformat and activate the screen using the screen layout editor (in this case we just moved one of the buttons and added user name to the bottom of the layout): BEFORE: http://blueharbors.com/customizing-sap-rf-mobile-screens/ 2/6 . com/customizing-sap-rf-mobile-screens/ 3/6 . These function modules are part of the exit function group XLRF. The naming convention for enhancements is MWMRFxxx (xxx = logical screen number). The standard data structures and any custom data fields will need to be added to the top include ZXLRFTOP.4/15/2014 Blue Harbors – Customizing SAP RF Mobile Screens AFTER: Next we need to implement user exits to populate the new field and perform any additional processing needed to support the business process. data: w_username type adrp-name_text. *&———————————————————————* *& Include ZXLRFTOP *&———————————————————————* include llmobdat. go to the components to see the before and after screen exits. as well as perform any additional processing needed. Once this is done. So in this case we need to create a new project in CMOD and assign enhancement MWMRF889. the same one we added the custom screen to above. The following code is added to the “before” exit EXIT_SAPLLMOB_720 (include ZXLRFU67): http://blueharbors. In this case include LLMOBDAT and a custom data field needs to be declared for the user name W_USERNAME. We need to transfer the “before” exit input parameters to the screen fields. in this case EXIT_SAPLLMOB_720 (before) and EXIT_SAPLLMOB_730 (after). the screen fields values need to be returned to the output parameters in the “after” exit EXIT_SAPLLMOB_730 (include ZXLRFU68): *&———————————————————————* *& Include ZXLRFU68 *&———————————————————————* o_rlmob_pback = rlmob-pback. logon_data-devty = i_logon_data_devty. o_rlmob_pmlgf = rlmob-pmlgf. go to Define Screen Management again and add a table entry for Variant ‘1’ to point logical screen to new exit screen. logon_data-lgnum = i_logon_data_lgnum. o_rlmob_psave = rlmob-psave. exit.com/customizing-sap-rf-mobile-screens/ 4/6 . o_logon_data_devty = logon_data-devty. o_logon_data_mmenu = logon_data-mmenu. rlmob = i_rlmob.

The same applies for the HTML templates so we can add company logos and such.htm Templates will need to be generated for all of the screens used in the company’s business processes.
