seperate Number range for SLFN, SDCR, SDHF txn

Hi,

I am doing configuration of service desk & CHARM. when I create a change request from Service desk it is assigning the no. 800000001 to support message & for change request it is 800000002 but I like to get different nos. for these two txn types.

SLFN for service desk no. should have to start by 800000001 on words.

SDCR for Change request nos. should have to start with 900000001 on words or any different than 8****.

SDHF also should have to different than the above two ranges.

I was defined the no Ranges in SNRO for CRM_SERVIC as 8000000001 to 899999999.

For CHARM /TMWFLOW/M no. 9000000001 to 999999999

/TMWFLOW/V ???

/TMWFLOW/D ??

Kindly suggest the best suitable solution.

Thanks & Regards,

Darshan
