Reading from other object

Question

Hi Guys,
I dont know whether am following the correct way , I have a scenerio where I have to show in the report Blocking reasons . I have a field from DS Payment Block Key which is 0PMNT_BLOCK in BI. I have 7 Blocking reasons in one table called BSEG and I have enhanced my 0FI_AP_4 DS to include this 7 fields and mapped to 7 BI Objects 0BLCKRSN_PR for price 0BLCKRSN_QL for quality....Now bringing these fileds from BSEG effecting performance as each time the exit is calling. I do have a Text data source (0PMNT_BLOCK_TEXT) which is having same data as I need...So in order to get this Blocking reasons in to my report without enahcing from BSEG table Iam trying to read it from master data . but its not allowing me to do that....When I say read from master data for one of the info object 0BLCKRSN_PR and press F4 its showing no info object available for reading of master data....Can any one tell me why its showing this error...I do have a Master data object 0PMNT_BLOCK which is having the values A B D H M P , so I want to read the above object 0BLCKRSN_PR from this Object ...as P is for Price and so on....
Do I need to take the seven info objects as attributes of 0PMNT_BLOCK ?
If so , I didnt find a DS for attributes in ECC , I have only Text DS 0PMNT_BLOCK_TEXT....
Please advice me what I need to do for this...Also please shoot me a reply If you ahve any more questions....

the join produces more rows then the sum of it's parts (e.g. 154). For example:
select owner, name
from all_source
where upper(text) like '%BINARY_INTEGER%'
633 rows selected.
select owner, type
from all_source
where upper(text) like '%PLS_INTEGER%'
926 rows selected.
select ds1.owner, ds1.name, ds2.type
from all_source ds1 inner join all_source ds2 on (ds1.owner = ds2.owner and ds1.name = ds2.name and ds1.type = ds2.type)
where upper(ds1.text) like '%BINARY_INTEGER%'
and upper(ds2.text) like '%PLS_INTEGER%'
5710 rows selected.
select owner, count(name) as name_cnt
from all_source
where upper(text) like '%BINARY_INTEGER%'
group by owner
OWNER NAME_CNT
SYS 577
WWW 56
2 rows selected.
select owner, count(type)
from all_source
where upper(text) like '%PLS_INTEGER%'
group by owner
OWNER COUNT(TYPE)
SYS 909
WWW 17
2 rows selected.
this could be a solution then:
select ds1.owner, ds1.name_cnt, ds2.type_cnt
from (select owner, count(name) as name_cnt
from all_source
where upper(text) like '%BINARY_INTEGER%'
group by owner) ds1 inner join (select owner, count(type) as type_cnt
from all_source
where upper(text) like '%PLS_INTEGER%'
group by owner) ds2 on (ds1.owner = ds2.owner)
OWNER NAME_CNT TYPE_CNT
SYS 577 909
WWW 56 17
2 rows selected.
