Lock a Table for Test Case

[Former Member]

Hi,

I read a little bit in the forum but didn't find exactly what I am looking for.

I have a couple of test cases that change data using RFCs from Ruby.

Is there a way I can lock a particular table or field.

Here is my test case

- read ADDRESSDATA.HOUSE_NO from BAPI_BUPA_ADDRESS_GETDETAIL

- change ADDRESSDATA.HOUSE_NO

- assert if ADDRESSDATA.HOUSE_NO was changed

- change ADDRESSDATA.HOUSE_NO back to the previous value

- assert if re-change was performed

I would like to prevent reading and writing the HOUSE_NO in between to avoid lost updates or dirty reads. What can I do?

Best,

Hi Stefan,

You can lock a table using FM:' ENQUEUE_E_TABLE' <b>or</b> if you want to a particular record, then you need to find out the lock object and the corresponding FMs for that table.

Example: To lock a reaord in PO item table EKPO ( Lock Object EMEKPOE),

CALL FUNCTION 'ENQUEUE_EMEKPOE'

EXPORTING

ebeln = ls_ekpo-ebeln

ebelp = ls_ekpo-ebelp.

write your update statements

CALL FUNCTION 'DEQUEUE_EMEKPOE'

EXPORTING

ebeln = ls_ekpo-ebeln

ebelp = ls_ekpo-ebelp.

Hi Chandra,

I tried to use ENQUEUE_E_TABLE with the structure name as parameter

CALL FUNCTION 'ENQUEUE_E_TABLE'

EXPORTING

TABNAME = "BAPIBUS1006_ADDRESS"

but it gives me the following error from which I don't know if it is an ABAP error or generated by the Ruby saprfc library.

Error: TABLE_NOT_ACTIVE

Might that be because BAPIBUS1006_ADDRESS isn't a table but a structure?

There is a second parameter for this function, namely VARKEY, that many people are using. But I couldn't find out what to give as a value. Do you have any ideas on this one?

Where can I find out how the explicit enqueue function for my structure is called (I am talking about the equivalent to ENQUEUE_EMEKPOE)?

thanks

Stefan
