Unfortunately the company I work for only allows IE! What kind of image or htmlhave you used that won't work with IE? It would be excluding allot of users I think...(I wish we could run a different browser.)

Can you please show the structure of ZATTR_CUST_TAB. As its not visible if you are already sharingit. The structure of the table doesnt have field like 'NEW'. So do we specifically add 'New' field instruct ZATTR_CUST_TAB.

Hi Sumeet..! I am new to CRM webui, found the most of the functionality in your article... I tried to impelmented thesame thing on my pc and got below errors.... 1) In IF_GENIL_APPL_ALTERNATIVE_DSIL~LOCK_OBJECTS lv_lovk_mode is unknown. it is not contaied in one of the specified table... 2)In class ZCL_CUSTOMER_API.. SAVE_CUSTOMER.. ABAP_BOOL is unknown... when I added the type-POOLs on the top the error is gone.. also in .. GENIL_MODEL_BROWSER when i enter the component as zcust, it neverallowed me to create the object when i right click on the root objects it shows collapseLower-level node and To Higher-level Node.... also in your sample it shows 4 symbols onthe top left corner to edit, transport (lorry), refresh and check but it is not showing me on myCRM 7.0 thing.. In my editor it is always a browser... not editor but in your screen shot it is saying as editor..like GenIL Model Editor: change component... etc I tried with t-code.. GENIL_MODEL_EDITOR it says it is not found.. When comming to the GENIL_BOL_BROWSER, I eneter the component name it showsempty model browser root objects... I believe this is because I could not create a root objectin genil model browser.... Again thnaks for your time in writing such a nice article but i do appreciate it if you clarify myproblems.. otherwise it would become an incomplete for me.. Thanks...

Savaridasan P Nov 20, 2012 5:37 AM (in response to Bala Bevara)

Greetings Bala, anyway Sumeet would be explaining you all in detail...to add with his point.. i too tried this document and got results..

thanks to Sumeet the second point u said its ok, i too faced it. and the document prepared using CRM 7.0 EHP 1 i think so. in CRM 7.0, you dont have Genil_Model_Editor transcation.

Hi Sumeet, Great Blog and Nice contribution.I am facing problem, when I tried to create a new root object in genil_bol_browser, programgenerating in short dump with the message A mandatory parameter was not populated when dyn. calling a method. Error analysis An exception occurred that is explained in detail below. The exception, which is assigned to class 'CX_SY_DYN_CALL_PARAM_MISSING', was not caught in procedure "CREATE_HANDLER" "(METHOD)", nor was it propagated by a RAISING clause. Since the caller of the procedure could not have anticipated that the exception would occur, the current program is terminated. The reason for the exception is: The mandatory parameter "IV_MODE" of the method "CONSTRUCTOR" of the class "ZCL_CUSTOMER_MODEL" was not populated during dynamic method call. I am using CRM 7.0. I don't understand how to pass "IV_MODE" value. Can any please help me onthis?

I could not see the root object in "ZCUST" component or "ZCSET_CUST" component set. No rootobjects are displaying when I tried to open them. Instead they are displaying in SO2component/component set.
