Number Range for Position Object for LSMW

I am trying to upload data for Position object through LSMW. I am using Tcode PP02. For testing purpose, I have created the upload file with just two records. While executing step 14, I faced the following error: "The number indicated is not in any valid external interval". While recording I had given the Position id (SEARK) as 50006510. In the upload file the values for Position Id's (SEARK) are 50006511 and 50006512.

In "Maintain Muber ranges" (Tcode OONR), the values for 01S subgroup are as below:

No. from Number To Number Current Number Ext

EX 00000001 49999999 Checked

IN 50000000 99999999 50009599 Unchecked

Please let me know where I am going wrong
