Batch determination in Pi Sheet

hi ,

i want to have batch determination in Browser based Pi sheet for components of process order BOM .we do not use X-steps.

i went through sap help :

Procedure

1. Enter the material quantity for which you want to find suitable batches in the PI sheet.
2. Place the cursor on the process instruction, for example, on the field for the material quantity or the batch, and choose Environment ®Batch®Find.

i could not find the environment in CO60 .

please guide if any one has done batch determination in pi sheet or if there is any other way to do batch determination in pi sheet.

i went through all the post regarding this in SDN but could not get the answer.

regards,

satish
