ORACLE execute error: ORA-01950: no privileges on tablespace ‘PDATA’

I’m new in Oracle, so maybe my question could be stupid. I use Oracle only for data storage. I have made some research but I’m blocked. I use Oracle 12c. I created a PDB with admin user PEEI_SYS like this:

create pluggable database PEEI admin user PEEI_SYS identified by PEEI  roles = (DBA); -- open PDB PEEI  alter pluggable database PEEI open read write;` 

I have created another user called PEEI which should only do select, update, insert on tables owned by PEEI_SYS. I have created the user PEEI like this:

CREATE USER "PEEI" IDENTIFIED BY "PEEI" DEFAULT TABLESPACE PDATA TEMPORARY TABLESPACE TEMP PROFILE DEFAULT ACCOUNT UNLOCK;` Now I would like that the user PEEI could insert rows in the table PEEI_SYS.PEEI_P_TRACKING. This table is created like this:  `CREATE TABLE PEEI_SYS.PEEI_P_TRACKING (  "CODE_WORKFLOW" VARCHAR2(30 BYTE),  "STATUS" VARCHAR2(15 BYTE),  "DATE_UPDATE" DATE,  "USER_UPDATE" VARCHAR2(20 BYTE),  "DEB_WORKFLOW" DATE,  "FIN_WORKFLOW" DATE,  "TIME_SECOND" NUMBER ) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT) TABLESPACE "PDATA" ; GRANT SELECT ON PEEI_SYS.PEEI_P_TRACKING TO ROLE_PEEI_READ; GRANT DELETE ON PEEI_SYS.PEEI_P_TRACKING TO ROLE_PEEI_WRITE; GRANT INSERT ON PEEI_SYS.PEEI_P_TRACKING TO ROLE_PEEI_WRITE; GRANT UPDATE ON PEEI_SYS.PEEI_P_TRACKING TO ROLE_PEEI_WRITE; 

When I got the error I granted unlimited privileges to PEEI user on PDATA tablespaces like this: ALTER USER PEEI QUOTA UNLIMITED ON PDATA; I have still the error. Could you please help me ? Thank you very much in advance. Kind regards, enter image description here
